概括
使用右小心胸切除术进行的最小侵入性 mitra 门修复,与胸腔切除术相比,更好地保持右心室 (RV) 功能,即使手术时间更长. 这种改善的RV功能是在手术后12周和1年观察到的.
科学领域:
- 心血管外科心血管外科
- 评估心脏功能的评估
- 最少侵入性手术的方法
背景情况:
- 右心室 (RV) 功能障碍是心脏手术后的常见并发症,与死亡率增加有关.
- mitra 门修复技术,特别是胸骨切除术与右侧小胸口切除术,可能会影响 RV 功能.
- 了解手术对VR功能的长期影响对于患者的治疗结果至关重要.
研究的目的:
- 通过右小胸口切除术对右心室 (RV) 功能进行关修复对右心室 (RV) 修复的影响进行比较.
- 为了评估RV功能中的变化,在手术前,12周和52周的时间点使用心声回声学.
主要方法:
- 随机对照试验 (英国迷你心脏关试验),比较右侧微胸切除术和胸切除术,以修复心脏关.
- 用于对心脏功能进行盲目评估的心声图谱,包括用于RV功能的三环状平面缩外流 (TAPSE).
- 由TAPSE评估的RV与肺动脉合的压力比率与缩性肺动脉压力比率.
主要成果:
- 在12周,两组都观察到TAPSE与基线相比显著降低,在52周部分恢复,但没有达到手术前水平.
- 通过TAPSE测量RV损伤的程度在12周 (1.47毫米差异) 和52周 (1.37毫米差异) 的右侧小胸切除组显着较小.
- 尽管微胸切除组的交叉和绕道时间较长,但RV功能得到了更好的保存.
结论:
- 通过右小心胸切除术进行的中枢修复显示,与胸骨切除术相比,右心室 (RV) 功能得到了更好的保护.
- 在手术后的早期 (12周) 和晚期 (52周) 评估中,VR功能保护的好处明显.
- 右小胸口切除术代表了对米特拉修复有关RV功能结果的潜在有利的手术方法.

Mitral Stenosis II: Clinical features and Diagnostic Tests
213
Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...

Mitral Stenosis I: Introduction

Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...

Mitral Regurgitation II: Clinical Features and Diagnostic Tests
356
Mitral regurgitation (MR) is a valvular heart disorder in which the mitral valve fails to close tightly, allowing blood to leak backward into the heart. Understanding the clinical manifestations, assessment, diagnostic findings, and medical management of MR is crucial to effectively managing affected patients.Clinical Manifestations of Mitral RegurgitationMitral regurgitation can be acute or chronic, each presenting differently and requiring different approaches:1. Acute Mitral...

Mitral Regurgitation I: Introduction
402
Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...

Mitral Regurgitation III: Medical Management
268
Mitral regurgitation (MR) is characterized by retrograde blood circulation from the left ventricle into the left atrium due to inadequate mitral valve closure. The severity of the condition, symptoms, and underlying cause determine treatment strategies.Monitoring and Pharmacological TreatmentPatients with mild to moderate MR typically do not need immediate intervention but regular monitoring to assess progression and guide treatment. Patients with mild MR should have an echocardiogram every 3-5...

Mitral Valve Prolapse II: Assessment and Management

IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular...
